VRM (Variable Range Marker) / EBL (Electronic Bearing Line)
The VRM/EBL is used to determine range and bearing of radar objects.
Variable range marker (VRM)
The VRM is a circle centered on one object and then adjusted so that the circle meets a second
object. The range between the 2 objects is displayed along the circle.
Electronic Bearing Line (EBL)
The EBL is a straight line from the center of the VRM to the edge of the screen and signifies the
bearing from the object in the center of the VRM to the second object which the EBL should pass
through.
